Description

The Square Reader is a white plastic square approximately 2.5 centimeters wide that connects to the headphone jack of a phone. With the Square app, the phone can read credit cards and accept payments.

Importance

Square did not charge for the reader and took a percentage of each sale, 2.75 percent in 2011. Small sellers, such as piano teachers and food trucks, could then accept cards without a merchant account. Jack Dorsey, a co-founder of Twitter, started Square with Jim McKelvey in 2009.

Interesting fact

McKelvey, a glass artist, lost a $3,000 sale because he could not accept a credit card for one of his glass faucets.
